ELLBER T FREMONT LONGWELL, OF NEW YORK, N. Y.

SKELETON SLUG FOR TYPE-CASTING MACHINES.

Specification of Letters Patent.

Patented Oct. 13, 1914.

Application filed April 11, 1911. Serial No. 620,318.

To all whom it may concern:

Be it known that I, ELBERT FREMONT LoNonfinL, residing in the borough of Brooklyn, county of Kings, city and State of New York, have invented certain Improvements in Skeleton Slugs for Type- Casting Machines, of which the following is a specification.

My invention relates to skeleton slugs which may be used in connection with type casting machines, affording shape, support and anchorage for a metal, alloy or other composition which may be cast, molded, or pressed through or into the holes or apertures provided for the purpose, and has for its object the production of a slug provided with holes or apertures at intervals spaced according to the width or set of the type size to be produced, thereby constituting the principal. and substantial portion of the type line so made.

A further object of my invention is to supply a skeleton slug provided with holes or apertures therein, into which a metal or other substance may be cast or molded and after having been used will admit of the discharge, by suitable means, of the metal introduced therein and which may then be used again and repeatedly for the purpose it was intended.

The foregoing and other features of my invention will now be described in connection with the accompanying one sheet of drawings, forming part of this specification, in which I have represented the skeleton slug in its preferred form, after which I shall point out more particularly in the claims those features which I believe to be new and of my own invention.

Figure 1 is a perspective view of my slug. Fig. 2, bottom view of my slug. Fig. 3, is a modification of slug shown in Fig. 1. Fig. 4 is a cross section of my slug associated with a melting pot and matrix, as when used in a type casting machine.

My invention consists of a skeleton slug 1 of any convenient shape or size, throughout its length with holes or apertures 2 at intervals determined by the lateral width or set of the type size to be produced on the face thereof. Its application is shown in Fig. 4 in which I represent a melting pot 3 provided with a specially constructed mouthpiece or jet 4 to fit the lower portion of the hole or aperture 2 in the slug. The matrix is shown at 5.

provided IV hen a line of printing characters are desired, the matrices singly and in turn are brought in front of the holes or apertures by any suitable means adapted to carry the slug past the casting point space by space and the alloy is forced into the holes one by one and the characters are thereby cast coordinately in the printing order desired, secured to the slug. The intention is to use these slugs over and over again. The discarded characters may be cut or melted out of the slug.

When holes are used as shown in Fig. 1 they are tapered from the bottom of the slug 6, where a groove 7 is provided forming two projections affording a clean and even support for the completed slug in a printing form and to eliminate the possibilities of burs or projections, left in casting from making an uneven base or foundation. Any further groove or shoulders may be provided as at 8, to cause the slug to conform to type sizes and structures. By this I mean the standard sizes and shapes for the body of the type and the manner in which the type is held in a printing form.

In F 3 I show a modification in which I provide a groove 8 on two of the sides of my slug located near the bottom edge, to accommodate the slug to a peculiar method of holding it in a printing form.

I am aware that slugs or printing bars have been used before for the purpose of supporting a line of characters, but I am not aware of the use of a skeleton slug to which the printing characters are separately and coordinately cast; and I therefore wish it distinctly understood that the following claims are intended to cover any modifications of my slug as naturally fall within the lines of invention.

I claim:

1. A skeleton slug provided with tapering holes extending through the slug transversely the length spaced according to lateral width or set of type size.

2. A skeleton slug provided with a top face adapted to receive printing characters, holes extending through the slug transversely throughout the length of the slugs and tapering toward the before-mentioned top face.

3. A skeleton slug provided with an edge adapted to receive printing characters and a series of tapering holes extending through the slug the axes of which are perpendicular to the edge of the small diameters of the v This specification signed and witnessed 10 holes in the plane of the. edge. at Room 1312, West Street Bldg, in the city 4. A skeleton slug consisting of a body of New York, this 10th day of April A. D., provided with a top faice anda bottom face I 1911. and provided with holes extending through the slug tapering; to the top face and provided with two projections on bottom forming a support for the completedslug in a 3 printing form.

Correction in Letters Patent No. 1,113,665.

It is hereby certified that in Letters Patent No. 1,113,665, granted October 13, 1914, upon the application of Elbert Fremont Longwell, of New York, N. Y., for an improvement in Skeleton Slugs for Type-Casting Machines, an error appears in the printed specification requiring correction as follows: Page 2, line 1, first occurrence, for the word of read and; and that the said Letters Patent should be read with this correction therein that the same may conform to the record of the ease in the Patent Oflice.

Signed and sealed this 5th day of January, A. D., 1915.
